DRAFT Student-written questions for BI 232 These questions have not been proofed, but they will still give you a good idea of range of topics that your peers determined to be important. This week, I will select a questions from the pool created by students from multiple lecture sections. These will be really valuable in preparing for the final exam. Stay tuned… From: Shelby L Jones Matching 1. lysosomes 2. Macrophage 3. Phagocyte 4. Osteoclast 5. kupffer cells A. sherical membranous bags containing digestive enzymes. B. Specialized cells of the reticuloendothelial system lining the sinusoids of the liver C. A giant multinuclear cell formed in the bone marrow of growing bones D. a large phagocyte found in lymph nodes and have the ability to ingest all foreign antibodies. E. A cell that has the ability to ingest and destroy particulate substances such as bacteria. 2. Which is not one of the five classes of antibodies a. Ig M b. Ig D c. Ig G d. Ig C e. Ig E 3. Blood in the left atrium ... a. flows out the aorta b. comes from the pulmonary veins c. is deoxygenated d. a and c E. B and C 4. Matching 1. Valve 2. Systole 3. infarction 4. pulse 5. diastole a. surge when the blood is pumped from the heart b. phase of the cardiac cycle in which heart muscles relax c. phase of the cardiac cycle in which heart muscles contract d. prevents backflow of blood e. death the myocardial tissue Darian Smith 1. Chapter 22: It's finals week and you have been studying for the anatomy & physiology final exam. What can you do to maintain the health of your immune system and prevent illness from ruining your much needed spring vacation? a) Pull an all-nighter cramming for the exam. Cramming information stimulates your limbic system which in turn causes the adrenal cortex to release cortisol, which complements the immune responses and helps clear antigens from your body. b) Blow off stress by taking a few shots of whiskey. The benefit of endorphins released while you are having a good time far outweighs the negative influence of stress on your immune system... plus as an added benefit, the alcohol kills some of bacteria already present in your body. c) See your doctor about getting an anti-anxiety prescription (like Valium). These medications strengthen your body's ability to handle stress. d) Get adequate sleep, eat healthy, regular meals, and practice stress management. e) Avoid the gym... Your brain has enough work to do just studying for the exam, save your energy for the exam. 2. Chapter 22: All of the following are characteristics of the lymphatic and immune system, EXCEPT: a) draining excess interstitial fluid b) transporting dietary lipids from the GI tract to the blood c) protecting against invasion through immune responses d) filtering lipids from the bloodstream and transporting these lipids to the GI tract for excretion e) ALL OF THE ABOVE ARE TRUE, NO EXCEPTIONS 3. Chapter 20: Your patient has complete blockage of a coronary artery. What arterial feature allows the heart to overcome this by providing oxygenated blood by means of an alternate route? a) anastomoses b) stenosis c) compensating capillaries d) reperfusion e) trabeculae carnae 4. Chapter 20: Your patient has tetany that has affected skeletal and cardiac muscles. The patient would: a) need an injection of epinephrine to cause caridac muscles to contract more forcefully. The forceful contractions would shock the system back into normal cardiac rhythm. b) need to be defibrillated. The strong, but brief electrical current would stop ventricular contraction, allowing the ventricles to refill and reset the autorhythmic cardiac cycle. c) be fictional. Cardiac muscles cannot undergo tetany because the refractory period is much longer in cardiac fibers than in skeletal fibers. Maintained contraction cannot occur once all the blood has been ejected to the next chamber or valve. d) require an immediate heart transplant. Cardiac tetany is fatal and irrepairable. e) should have arterial blood drawn and tested for the presence of creatine kinase (CK). Cardiac tetany is a symptom of myocardial infarctions. BONUS QUESTIONS 5. Chapter 18: Jefferson Airplane sang "One pill makes you larger / And one pill makes you small / And the ones that mother gives you / Don't do anything at all / Go ask Alice / When shes ten feet tall..." We asked Alice what sort of pills she took and how old she was when she took them, but she was too drugged to tell us anything useful. Given your understanding of the endocrine system and growth and development, which statement best describes what Alice may have taken? Alice took a medication that __________ the effects of _________ which __________. In addition, Alice must have taken the pills __________. a) simulates; hGH; stimulates the release of insulin-like growth hormone resulting in increased skeletal & muscular growth; before puberty. b) negates; PTH; allows the bones to grow longer and stronger which in turn can lead to gigantism; in enormous doses. c) enhances; estrogen; encourage growth at the epiphyseal plates; after puberty. d) blocks; calcitonin; encourages the growth of long bones by increasing the bones' Ca+ uptake; before puberty. e) inhibits; TSH; stimulates the body's metabolism, increasing the speed of bone cell mitosis; before puberty. 6. Chapter 20: Match the following EKG phases with the descriptions: PQ interval ST segment QT interval P wave T wave This represents the conduction time from beginning of atrial excitation to the beginning of ventricular excitation. the time required for the action potential to travel through the atria, the AV node, and the remaining fibers of the conduction system. This represents the time when the ventricular contractile fibers are depolarized during the plateau phase of the action potential. This is elevated in acute MI and depressed when the heart muscle receives insufficient oxygen. This represents the time from the beginning of ventricular depolarization to the end of ventricular repolarization. This may be lengthened by myocardial damage, myocardial ischemia, or conduction abnormalities. This represents atrial depolarization. This may be larger which may indicate enlargement of an atrium. This represents ventricular repolarization. This may be relatively flattened when the heart muscle is receivinginsufficient oxygen, or it may be elevated when there is a high level of potassium ions in the blood.
